17.5 Yep that's 17.5!! Had a bit of a meltdown last night and did overdo the carbs but I did Bolus accordingly. However when I went up to bed I noticed a very unexpected sharp upward arrow on my Libre. I checked my cannula and the stuff that sticks it down was covered with lots of very fresh blood - I've never had that happen before. So a perfect storm of high carbs and a dodgy cannula.
